No. 475,921. Patented May 31, 1892.

NITED STATES ATZE'NT BENNY BERNSTEIN, OF NEW V YORK, N. Y.

SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 475,921, dated May 31, 1892.

Application filed November 20, 1891. Serial No. 412,534. (No model.)

To all whom it may concern.-

Be it known that I, BENNY BERNSTEIN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Window-Shutter Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in window-shutter fastenings; and it has for its object to provide a device which will hold the shutter in an open or closed position, which will be automaticin both of its locking operations, which cannot be operated from the outside to open the shutter when closed, and which is simple and inexpensive in construction and may be readily applied to a shutter of the usual construction.

The invention consists in the combination of an externally screw-threaded block having a head at one end, a longitudinal opening through it, and a lock-lever fulcrumed within, of a keeper having flaring mouth with open curved lips adapted to be secured to the sill of a window, and a staple or fastening adapted to be secured to the wall of the buildin g, thelock-lever being formed with a latch at one end to engage the staple and with a swiveled-weighted bar at the other to engage the keeper, as more fully hereinafter described, and specifically claimed.

In the accompanying drawings, forming part of this specification and in which similar reference letters and numerals indicate like parts in the respective figures, Figure 1 represents a vertical sectional View of a window frame and shutter, showing my device, the shutter being in aclosed position and locked by said device. Fig. 2 represents a longitudinal vertical sectional view through the block and a portion of the shutter, showing the lock-lever and keeper in side elevation and in a locked position. Fig. 3 represents a horizontal sectional view through the block and a portion of the shutter, showing a plan view of the lock-lever and keeper in alocked position. Fig. 4 represents an end elevation of the device, showing the weighted bar as just about to enter the keeper or escape therefrom. Fig. 5 represents a horizontal view of a portion of the wall of a building, windowframe, and shutter, showing the shutter locked in an open position; and Fig. 6 represents a view similar to that shown in Fig. 3 with the lock-lever disengaged from the staple on the wall.

Referring to the drawings, the numeral 1 indicates a cylindrical metallic block externally screw-threaded and provided at one end with a head 2. The said block has an opening extending longitudinally through it, which is flared at each end, as shown in Figs. 3 and 6, to permit the proper movement of thelocklever.

The numeral 3 indicates the lock-lever, which is fulcrumed at 4 within the block, as shown in Figs. 2, 3, and 6. The outer end of said lever is flattened and recessed, as indicated by the numeral 5, so as to form a catch to interlock with a staple 6, which is adapted to be attached to the wall of a building, and is so shown in Fig. 5 of the drawings. The inner end of the lever is rounded and its extremity contracted, forming a shoulder 7 and upon the contracted portion of said bar is swiveled the sleeve 8 of a weighted arm 9, the sleeve being held in abutment with the shoulder by means of a screw or by upsetting the metal at the end of the lock-lever.

The numeral 10 indicates a keeper, which consists of a standard having a suitable base, which may be attached to the base of the window-sill, as shown in Figs. 1 and 5 of the drawings. The upper part 01": the standard is provided with curved open lips 11, the opening between the same being of less width than the diameter of the inner end of the locklever, so as to preventits passage between the same, but of greater diameter than the weighted arm, so that said arm will pass readily between the lips, as hereinafter explained. The sleeve of the weighted arm next to the shoulder on thelock-lever is provided with asmall pin 12, which projects from the contracted portion of the lock-lever to prevent the weighted arm from being raised above a horizontal position, and the upper lip, at the rear, with an extension 13'to guide the weighted arm into and out of engagement with the lips as ICO the shutter is closed and opened. The block 1 is screwed into an opening through the shutter 14:, which is formed through the same for the purpose, as shown in Figs. 1, 2, 3, and 6 of the drawings. When the shutter is fully open, the outer end of the lock-lever engages the staple secured to the outer wall of the building, the outer end of said lever being beveled, so as to ride automatically over said staple in throwing back the shutter to such position. In closing the shutter the weighted arm rides between the lips of the keeper until it passes behind them, when it drops into position shown in Figs. 1, 2, and 8, locking the shutter in a closed position.

The lock-lever may be operated to release it from the staple for closing the shutter by moving the end of such lever carrying the weighted arm laterally, as shown in dotted lines in Fig. 3 and full lines in Fig. 6. To open the shutter, the weighted arm. is raised to a horizontal position, as in Figs. 4 and 6, and pushing the shutter outward.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. In a shutter-fastener, the combination of ablock havingalongitudinal opening through it, a lock-lever fulcru med therein and projecting at each side, the outer end being formed with a catch to engage a suitable staple and the inner end provided with a swiveled weighted arm adapted to engage a suitable keeper, substantially as specified.

2. The combination of the screw-threaded block, the lever fulcrumed therein, the staple adapted to be engaged by the outer end of the lever, the Weighted arm swiveled to the inner end of the lever, and the keeper having open curved lips, substantially as specified, the opening between the lips being of less width than the diameterot the lock-leverand of greater width than the diameter of the weighted arm, for the purposes set forth.

3. The combination, with thelock-leverand the weighted arm, of the keeper having flaring mouth and curved open lips, the upper one having an extension at its rear to guide the weighted arm into and out of a locked position, substantially as specified.

4. The combination, in ashutter-tastener, with the lock-lever secured to the shutter and having a swiveled weighted arm at its end and keeper secured tothe window-sill having flaring mouth and curved open lips, of means for limiting the upward movement of the arm, for the purposes specified.

In testimony whereof I atfix my signature in presence of two witnesses.
